Question

Garrett is 47 years old, and Emily is 29 years old. How many years ago was Garrett's age 3 times Emily's age?(A) Let  represent how many years ago Garrett's age was 3 times Emily's age. Write an equation that expresses the relationship between the ages of Garrett and Emily  years ago. Your equation should be an explicit model of this relationship, so your equation must contain 47, 29, and 3. Do not simplify your equation.

Answer 1

G-x = 3(E-x)

G=47

E= 29

47-x = 3(29-x)

x=20

20 yeas ago G=27

20 yeas ago E=9

47-20 = 3(29-20)

27=3(9)
